[ 32/48] hwmon: (sht15) Fix memory leak if regulator_enable() fails

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



3.4-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Ben Hutchings <ben@xxxxxxxxxxxxxxx>

Commit 3e78080f8148 ('hwmon: (sht15) Check return value of
regulator_enable()') depends on the use of devm_kmalloc() for automatic
resource cleanup in the failure cases, which was introduced in 3.7.  In
older stable branches, explicit cleanup is needed.
